Thank you! It can be a bit difficult to come up with new ideas for this pairing these days, so you calling this twist on time travel "original" makes me very happy.
In the end, though, having to make that choice was what would make it all work, I think, so far as Harry and Snape were concerned.
Yeah, I agree with that. Harry's always been resentful when he's not given a choice. And Snape needed to know that Harry was actively choosing him.
I'm glad all the side characters worked, and I had a lot of fun with Albus (even though he can be a frustrating old coot at times). The fact that you were still thinking about the story after reading it is a huge compliment, as is your "propelled onward" remark!
Thank you again! Having the first comment on this fic be such a detailed one just made my day. :)
